 useful in generation because they contain non-reproducible hash strings.

 <p>This method is actually more restrictive in what it determines to look like it came from
 Object.toString(): it deems anything that has a substring matching the pattern
 <code>@[0-9a-h]{1,8}</code>. Meaning, if it looks like the string contains the <code>"@&lt;em&gt;hex&lt;/em&gt;"</code> pattern, the method returns true. This almost always works and is a faster

 <p>If Randoop generates tests using strings that are too long, this can result in
 non-compilable tests due to the JVM's limit on the length of a string.

 <p>A string S is too long if, when printed as code in a generated unit test, it may result in a
 non-compilable test. In order to determine this, we have to consider not the length of s, but
 the length of the string that would be printed to obtain s, which may be different due to
 escaped and unicode characters. This method takes this into account.</div>
